U.S.-U.S.S.R. Workshop on Solar Activity, Solar Wind, Terrestrial Effects and Solar Acceleration (Dagomys, USSR: October 15-20, 990)

美国和苏联最近和计划进行的关于日地现象的研究，以及苏联科学研究环境的更大开放性，使得两国在这一领域举行科学研讨会显得尤为及时。该研讨会将在苏联举行，将集中讨论四个主题：太阳活动，包括太阳周期的表现；太阳风，包括太阳风的来源和大、小结构的理论和演化；陆地效应，例如磁层响应以及电离层和磁层扰动的地面研究；太阳加速，包括太阳宇宙射线的起源和传播，与太阳活动和地球效应有关。所有这些事件的研究，特别是事件链的定量重建，需要整合多个学科的知识。从太空和地面数据中获得了关键的理解，美国的研究分别由NASA和NSF赞助。无论在美国国内还是国际上，这个研讨会都将是为数不多的审查整个日地链的研讨会之一，因此将有助于为协调美国的空间和地面研究计划设定目标。该研讨会由美国国家科学院和苏联科学院联合组织。美国代表团将由特拉华大学巴托尔研究基金会主席诺曼·f·尼斯博士率领。苏联代表团将由苏联科学院地磁、电离层和无线电波传播研究所所长Viktor N. Orayevskiy博士担任主席。在美国方面，该项目由NASA和NSF联合支持。该项目实现了推进科学知识的计划目标，使美国和苏联的领先研究人员能够在平等、互惠和互利的基础上，在共同感兴趣和有能力的基础科学研究领域结合互补的努力和能力。

Recent and planned research by the U.S. and the U.S.S.R. on solar-terrestrial phenomena, as well as the greater openness in the Soviet scientific research climate, make it particularly timely for the two countries to hold a scientific workshop in this area. The workshop, which will take place in the U.S.S.R., will focus on four topics: Solar Activity, including solar cycle manifestations; Solar Wind, including the sources of solar winds and the theory for and evolution of large- and small-scale structures; Terrestrial Effects, such as magnetospheric responses as well as ground-based studies of ionosphere and magnetosphere disturbances; and Solar Acceleration, including the origin and propagation of solar cosmic rays as related to solar activity and terrestrial effects. The study of all these events, and particularly the quantitative reconstruction of the chain of events, requires the integration of knowledge from several disciplines. Crucial understanding is acquired from both space- and ground-based data, research on which in the U.S. is sponsored respectively by the NASA and NSF. This workshop will be one of very few, either within the US or internationally, that review the entire solar-terrestrial chain and thus will have the added benefit of helping to set objectives for the coordination of the U.S program of space- and ground-based research. The workshop is being organized jointly by the U.S. NAS and the Academy of Sciences of the U.S.S.R. (ASUSSR). The U.S. delegation will be led by Dr. Norman F. Ness, President of the Bartol Research Foundation, University of Delaware. The Soviet delegation will be chaired by Dr. Viktor N. Orayevskiy, Director of the ASUSSR Institute of Terrestrial Magnetism, Ionosphere, and Radio Wave Propagation. On the U.S. side the project is being jointly supported by NASA and NSF. This project fulfills the program objective of advancing scientific knowledge by enabling leading researchers in the U.S. and U.S.S.R. to combine complementary efforts and capabilities in areas of strong mutual interest and competence in the field of basic scientific research on the basis of equality, reciprocity, and mutuality of benefit.
